I'm working on a program to draw land leases from metes & bounds, but I'm getting small closure errors, presumably due to the earth's curvature. For example, at a latitude of about 40 N, I head straight east for 10,000 ft along a great circle, then due south for 10,000 ft (which should be along a meridian, yes?), then west for 10,000 ft and from there back north for 10,000 feet. I end up at a point about 5.7 feet south and a little east of my Point of Beginning.
How do real surveyors deal with this problem? Is there some sort of regular correction applied to bearings or traverses? How is it done? - Bill Thoen --------------------------------------------------------------------- List hosting provided by Directions Magazine | www.directionsmag.com | To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] Message number: 13959
